A 49-year-old man recovering from drug addiction at a rehabilitation centre here in North 24-Parganas was allegedly beaten to death on Tuesday night by a section of its officials apparently because he had secretly called his brother to inform him about the ill-treatment meted out to him and other inmates.

Police have arrested two accused officials — Subhankar Mondal and Subhashis Chakraborty — on murder charge whereas the owner of the Su-Drishti Darshan Rehabilitation Centre is yet to be traced.

The Nimta police have begun a probe on the basis of a complaint lodged by the brother of the victim, Partha Raha.

Raha, a resident of Birati Kalabagan area, was brought to Ghola Hospital at Sodepur on Tuesday night with multiple injuries, including one to the head.

He was declared brought-dead by the hospital officials, who informed the police about the unnatural death.

Deputy commissioner (south) of Barrackpore Police Commissionerate Ajoy Prasad said: “We have received a written complaint from the victim’s family and began a probe. Two persons have been arrested. Police are in search of another accused person.”
